2007 BMW 3 Series 335i 4dr Sedan (3.0L 6cyl Turbo 6M)
My 6 speed 335i ZSP sedan was purchased used as a CPO. The power's nice, the fairly sharp handling is rewarding (nice to be back in RWD) and the is quite cocooned. Large trunk, decent gas mileage and large backseat make it a good family car (wife and infant son). I look forward to curves. Sadly, the vehicle is extremely heavy, the RFTs are lousy and the interior trim appears to be peeling away on the door handle and steering wheel. It's a fun enough car but I look forward to the day I won't need something so large; I'm anxious for BMW to produce a light RWD coupe/sedan. For the next few years the 335i will suffice.
RWD and near 50/50 weight distribution. Fairly good power to weight ratio.
Lose 400-500 lbs. Replace RFTs with real tires. 17 inch tire option on sport package. Replace navigation system with something useful and integrated with a cell phone/Google maps. An exhaust that actually has something throaty to say - like the departed e46 ZHP models.
